Ben Dalling commented on CASSANDRA-9822:
----------------------------------------

We experienced the problem with both 2.1 and 2.2 (package installs) on Ubuntu 
12.04 and 14.04.  As a temporary workaround, changed the search string from 
"cassandra.+CassandraDaemon" to simply "cassandra" and the service status 
command worked as expected.

> Debian/Ubuntu init script status says that Cassandra is not running when it 
> actually is

> The reason: The current CMD_PATT regex can't match very long command lines.
> If a lot of Java options are used (thus causing the command line for 
> Cassandra to be very long) the value of /proc/PID/cmdline is truncated before 
> the phrase "CassandraDaemon" (at exactly 4096 characters) so the regex 
> "cassandra.+CassandraDaemon" fails to match.
